can I revert to the jaunty 9.04 release, 9.10 is giving me problems?

I don't think you can go back to 9.04 unless you do a fresh install. but you can try to solve this problems. try first to update the distro for me it helped to detect the soud and the touchpad (they did'nt work when I upgraded) than look in the forums for solutions to each problem you can also report bugs if they don't already exist.

Hi,

if you want to risk at your own, you could try to substitute all the words "karmic" into "jaunty" from your sources.list: I'm not sure this will work neither it won't cause you any damage.
Anyway, if it should work out, by time you downgrade you've already reinstalled Jaunty, applied all the updates and setted up Ubuntu how it was before Karmic.

So, I suggest that you do a fresh install. ;)

Alright try this first:

sudo apt-get update
sudo apt-get upgrade

Now that you system is updated, there were a lot of bug fixes that were
released so that might just work. Alright after that right click on your
desktop and then go to change desktop background -> then to visual effects and
then click on none. Compiz is creating a lot of regression so that might be
the major problem. Regarding the external hard drive unplug it and then plug
it in again.

If none of your problems are fixed and you want to switch back to jaunty you
have to do a fresh install. But let's hope all your problems get solved

Thanks Vikram,

things are definitely looking better, and my external drive is visible again.

I don't know if all is fixed, it can take anywhere from 5 minutes to an hour to freeze up, will update later if all is OK.

Well,

I hate to say this, but I can't get this system working. It is definitely software, it has been many long days, and I give up, it is almost unbelievable to me that I am going back to Windows. I just can't work with my PC freezing every 15 minutes or so.

It was good while it lasted, but I am kissing Ubuntu goodbye.

Thanks for trying to help...

I have the same problem as you, so I went back to 9.04 but had to do it the hard way starting with 8.04 which was the only disc i had. When I loaded 9.10 from Update manager I had a boot-up problem and the freezing as you do. The boot stopped about halfway through but strangely if I went into boot menu and selected hard disc it worked. Eventually I did a new install from an image disc I burnt (using my XP computer) and also from a 9.10 disc I got from Canonical. This solved the boot problem ( which I put down to a glich in the original download). But the freezing persisted, even with the Canonical disc. I have looked around a lot both on Ubuntu website, launchpad and on the Dell website (this a Dell computer). This problem of freezing is not new and certainly pre-dates 9.10; the earliest reference to it I found was in year 2007! The problem appears to be more prevalent with Dell computers, both desktop and laptop/notebook. I am now back on 9.04, looking for the confidence to update to 9.10 again, hoping the problem would have been solved by now. I am fairly sure the problem is to do with keyboard/mouse rather than the computer freezing - without going into detail here I have had indications that the system is still active with the screen frozen but the only way out of it is to cut the power and I do not like doing that too often. Is there any one out there who can help!! Eventually i will retry 9.10 but now I have a disc of 9.04 so I can quickly reinstall if still does not work. And I have not even started on my wifes (Dell) computer which is also on 9.04!
